Therefore, GCD of numbers 650, 805, 65, 868 is 1

Given Input Data is 650, 805, 65, 868

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 650 is 2 x 5 x 5 x 13

Prime Factorization of 805 is 5 x 7 x 23

Prime Factorization of 65 is 5 x 13

Prime Factorization of 868 is 2 x 2 x 7 x 31

The above numbers do not have any common prime factor. So GCD is 1

Step1:

Let's calculate the GCD of first two numbers

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(650, 805) = 104650

GCD(650, 805) = ( 650 x 805 ) / 104650

GCD(650, 805) = 523250 / 104650

GCD(650, 805) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 65

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(5, 65) = 65

GCD(5, 65) = ( 5 x 65 ) / 65

GCD(5, 65) = 325 / 65

GCD(5, 65) = 5

Step3:

Here we consider the GCD from the above i.e. 5 as first number and the next as 868

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(5, 868) = 4340

GCD(5, 868) = ( 5 x 868 ) / 4340

GCD(5, 868) = 4340 / 4340

GCD(5, 868) = 1

GCD of 650, 805, 65, 868 is 1
